Had a look at a split load 17th edition RCD CU, quite new - one of the sides has a solid copper neutral that runs off to the Neutral bar on the DP isolator of the CU. Basically, due to a loose connection, a bit of Arking has gone on and made a mess. I want to put a new Neutral in to replace the damaged one - what is the CSA of the conductor used in these CU's (it's just a solid copper bar that has blue insulation and bends around the back of the MCB's) I want to replace it with some new cable, the DP switch is rated at 100A on the CU. I'm thinking it may be 16mm, just want some advice please. Also - would this just be a maintenance issue or should i issue a MW also?
